在用柴油车污染物排放检测研究

Study on Pollutant Emission Detection of In-use Diesel Vehicles

随着环境污染的日益加剧,对于在用柴油车排放污染的治理标准也越发严格。文章介绍了自由加速、加载减速和遥感三种在用柴油车排放检测的方法,通过梳理我国在用柴油车标准的发展进程,对比了不同时期标准在用柴油车排放的限值,有助于了解我国在用车检测限值、检测内容及检测流程的变化,明确未来国家对在用柴油车排放污染治理的趋势。

With the increasing pollution of the environment,the pollution control standards for in-use diesel vehicles are becoming stricter.This paper introduces three methods of diesel vehicle emission detection:free acceleration,lug-down mode,and remote sensing.By combing the development process of China’s in-use diesel vehicle standards,it compares the limits of standard in-use diesel vehicle emissions in different periods.It is helpful to understand the changes in the detection limit,content and testing process of in-use vehicles in China,and clarify the future trend of the country’s pollution control of in-use diesel vehicles.
